Gadget/funny stocking fillers?

He is at the age where he has asked for clothes as main presents and new trainers so we have those, the ones he wants thou are so expensive so didn't look a lot.

So I wanted to spend some money on getting him some smaller presents. To have some fun with iyswim. I have 8 in total mainly sweets/chocolates (giant jelly baby, Thornton's choc). Also have a gobstopper machine, YouTube book, magnetic putty.

Basically ran out of ideas but would ideally like a few more bits, no more than £10 ish each.

He likes little gadgets, and funny joke type things. I have had a look on amazon for ideas but many either seem 'babyish' for his age or 'rude' and too old for his age, so just turning to MN's to see if any wise ideas

No that's great thank you. Trouble we have is his birthday 6 weeks before Xmas where he got many of what you suggested. I just find it a difficult age! Is he too young for aftershave? Something like joop maybe? He has a squirt of his dads for special occasions!!
